| Abstract:
In cultivated saffron (Crocus sativus L.) various kinds of contractile roots are formed. The most important of contractile roots are produced at the terminal buds. From corm fragments carrying bud protuberance, in MS culture medium containing 2,4-D (0.5 mg/l) and kinetine (9 mg/l), contractile roots are formed and then contracted at the base. Phenolic compounds specially paracomaric acid have positive effect on their formation, growth and contraction. | |
